The transfer case of the Toyota FJ Cruiser in the photo, for example, takes only 1.5 quarts (1.4 liters) of SAE 75W gear oil. In this case, the transfer case fluid level should be checked, and if the transfer case is full, the manufacturer may even consider slight seepage normal. In most vehicles, a transfer case is filled with a small amount of gear oil (usually SAE 75W-85, 80W-90 or 75W-140 grade). The fluid level and condition can be checked through the fill plug. The transfer case or unit usually has two plugs: a fill plug above and a drain plug below. Your mechanic can check the fluid condition first and change it if it's dirty. Repeat the same procedure as the transfer case and youre done. Rear diff is much easier-the drain plug is on the bottom of the case, the fill plug is on the drivers side and easy to see and get to. The fluid should also be changed if the transfer case has been submerged in water. Use the pump to refill the case until fluid starts seeping back out of the fill, replace fill plug, and move on to the rear differential. In our opinion, even for normal driving conditions, the transfer case fluid should be changed at least every 60,000-70,000 miles or sooner if so recommended in the maintenance schedule. See this photo of the inside of a failed power transfer unit at 105,000 miles. In many cars, a transfer case is located close to hot exhaust components the heat also causes the fluid to deteriorate sooner. Toyota transfer case drain plug and fill plug.
